Fairenuff "if you are giving money which is not earned, then it's not pocket money."
Surely a question of semantics? To me pocket money is money given by parents to children to spend on sweets, comics, whatever. It's not conditional although of course you can make it conditional if you wish - you're the parent.
Also "But the UP way is optional from the start, right?"
Not really. But it's not about the one person - the child. It's a different way of looking at it completely. Housework isn't an option. Somebody has to do it, and within a family it's the responsibility of everyone in that family to do it. I'm pretty crappy at keeping up with it if I'm honest, and DS is only 4, so fairly often we do get to the point where it's necessary rather than preferable to get stuck in and do stuff. It's better when DP is around 
I don't force him to help, no, but he quite often offers to help of his own accord, and at various times he's asked me to play or do something for him and I've said well I have to do this at the moment, but if you like, you could help me and then it will get done quicker and I'll be able to play/help/whatever. And sometimes he does, sometimes he doesn't. Sometimes he's annoying the crap out of me and I say look, if you're going to be down here then help me, if you don't want to help then please find something to do, but stop hanging around asking me questions which I keep repeating the same answers to.
Also it's just about taking advantage of the little interests they have when they're tiny so that helping becomes easier when they're older, and trying not to get annoyed/frustrated when they're more of a hindrance than a help, seeing it as a long term investment rather than a short term thing. Like when DS pulled the washing machine drawer out mid-cycle when he was 2 and spilled half dissolved powder everywhere, my first instinct was "Aaaargh look at the mess!" but instead I thought, well, he was probably trying to help/copy me, so I showed him how the drawer worked properly, and how and when to put the powder in and let him help after that by putting the powder in when I ran a wash load. He never tried to pull the drawer out by himself again, and now he knows which line the powder needs to come up to and where it goes.
Similarly one day when DP was here I was sorting some clean laundry out into piles and DS came up and I was really antsy because he didn't even notice the piles and was happily walking all over them, tripping on them, picking up random clothes to use as a cape, whatever. DP called up the stairs "Let me know if you want me to come and get him" and I was getting annoyed and was about to call him when I decided to try and see if he was actually interested or just wanting me to do something else, so I explained (in a really strained way if I'm honest) that I was sorting this into Daddy's pile, this into Mummy's drawer, etc, and oh look, can you see if there's another sock that matches this one in that pile? etc. And he ended up helping - ok it wasn't any quicker than me doing it myself, but now he's learned that socks need matching up and that they don't appear in his drawer magically paired. That when the clothes come out of the machine they're all mixed up and somebody has to sort them out and put them into piles/drawers and that if we treat them nicely they look all smooth but if we just scrunch them, then they get crumpled and need ironing (which by the way he loves the idea of, but I won't let him touch until he's big enough and co-ordinated enough to control the iron safely!)
I'm not hopelessly naive and I'm sure that at some point in the next few years he's going to twig that housework is pretty boring and mundane, but at least he knows that it has to be done and maybe a bit about what it entails, rather than vaguely thinking that the housework fairy does it all.
Also although UP is against praise per se it's not saying that you can never express pride or say anything which is vaguely affirming. I'm pretty sure UP doesn't say that you let your child choose for themselves the safest way to cross a road - if it does, that's stupid.
